I just built a Video Editing & VFX system on a TRX40 platform with 256GB RAM (32gb x 8, 3200MHz) – and it looks like windows is only picking up half of it. This is my 2nd build and is very easy to adjust and access. Temps are good, BIOS is up to date, and I just checked all DIMMs & Modules as well as the pins on the processor - Everything is looking sharp on the hardware front (brand new).
• Bios, Task Manager, & CPUz/HWInfo show all 8 sticks at speed, and whether I run the XMP profile for the 3200 speed or set them to default, I get the same result – with my task manager showing 256GB installed but only 128GB Hardware Reserved and available. When Running 4 Dimms it shows 128 with 128 available, and seems fine.
• I checked my boot option in msconfig and it is not limiting my RAM
• I checked BIOS for iGPU settings, but there is no onboard graphics card to mess with and I cannot find a spot to disable anything in BIOS.
• This motherboard supports Quad Channel memory, up to 32GB x 8 @3200, the matched set of G.Skill Ram I have installed is on the supported QVL list from the motherboard manufacturer’s Website (Asrock).
I have searched online & made several BIOS adjustments to no avail, and this limited ram issues has me quite perplexed. I am thinking this might be a simple fix for someone smarter than me, but not sure if it can be diagnosed from the info provided.
I am not sure if I need to disable something in BIOS, but all of my components should play together nicely:
If you want to try before you buy you can do a full reinstall as Pro. I think you can run it that way without a license for months before it starts to get really upset at you.
But I think if you upgrade an existing licensed Home to Pro it will want your money right away…I could be wrong about that.
$200 oversight on pro vs home, whoops. I can’t believe i did not even know to check that. I may try for the test “reinstall” and forget my product key. I will post back if it works. So far the machine is performing stable and great for my needs even at the 128, but I just cant let well enough alone.
Out of curiousity, are there similar limitations with linux and other OS options?
It is quite posible to change the windows 10 edition without reinstalling. I have done it myself a number of times.
Stick in a KMS key, and it will upgrade no problem. W269N-WFGWX-YVC9B-4J6C9-T83GX for win10 pro

In general, no. It is possible that there is an exception if you are buying Linux from someone Oracle, they might have limits. But something like Debian the limit is theoretical, limited by what the hardware out at the time of release can support.
Well yeah, there are Linux build options that do put limits on things. They are generally ridiculously high and you can always rebuild if you need to. Although in some cases you’d have to write the new code yourself.
For Linux, the last I knew, the regular 64 bit kernels are limited to around 2 TiB RAM and 4,096 processor threads. There are also limits on the number of PCIe slots, SATA or SAS ports, USB devices, etc.
You should install linux if you can use it for your use case. Not sure what video editing suit you’re using. Windows has artificial limitations on processor count and memory quantity which i think is bordering on evil.
I ran into this issue on a quad socket machine that I bought used, because windows 10 Pro only supports two sockets. i ended up having to buy a license for windows server and it makes me made every time I think about it. Now there is pro for workstations that (I think) can do more than two sockets.
happy days…
